Selig Barcelona Chair Cushion Conundrum!  

I just could be mistaken.
It's happened before. I know nothing about chrome plated Knoll Barcelona products. So sorry.
Best of luck,
Mark.

Look for small k or p stamps ...
Look for small k or p stamps all around your chairs, mine are on the outside of the rear brace. It took me a long time to find them, and not all authentic knoll barcelona chairs have them. Mine are stainless.
Pictures would help.

Barcelona Chair Cushions
I am sure this is probably a Chinese company. You can decide what you think about that. But they make cushions at a very low cost.

I just got a really great quote from the owner of this website. We are providing our own fabric. The cost for 2 cushions is $275-$325 for both. Check out her work. She is good! http://www.klupholstery.com/#!upholstery-gallery2/c1c4o

Just wanted to spread the word since a lot of you are looking for cushions and straps. This Canadian company ships pretty good quality cushions and straps across North America. My cushions came through a bit late but by the time I got them I was pretty happy. I've attached some pics below and their link.
